Modeling dependent risk factors with CreditRisk+
In this paper, an extension of the CreditRisk+ model, called the mixed vector model, is proposed.
Contributions to credit risk
Optimisation of credit portfolios requires that risk contributions be quantified. However, there has been disagreement over which of three popular tail risk measures should be used. Here, Alexandre Kurth and Dirk Tasche offer a way forward, showing how…

Waiting for guidance
South Korea's banks have made huge strides in implementing risk management systems over the past few years, but Basel II is not yet a driving force, with banks waiting for the Korean regulator to publish local guidelines.

Analytical approach to credit risk modelling
The increasing popularity of VAR-based credit portfolio risk models has led to a growing recognition that Monte Carlo techniques are inadequate for economic capital calculations. Here, Michael Pykhtin and Ashish Dev present a new analytical alternative…
Probing granularity
The granularity adjustment, which adjusts risk weightings for credit portfolio diversification, is one of Basel II’s key modelling assumptions. Here, Tom Wilde uncovers a weakness in this assumption arising from the differences in the underlying credit…
